Security — entry 029 of 30
URLhaus
URLhaus, part of the abuse.ch project run out of Bern, Switzerland, crowdsources and publishes malware-distribution URLs so security teams and blocklist maintainers can flag or block them before they're weaponized further. The community API covers both querying (recent submissions, per-URL/host/payload lookups) and submitting new malicious URLs, with results also available as CSV dumps, MISP events, and Suricata/Snort rulesets for direct feed ingestion. Since 2023 every request needs a free Auth-Key from the abuse.ch Authentication Portal; a paid tier layers on higher reliability and a unified query language across abuse.ch's other feeds.

Auth quickstart
- Sign up with the provider to get an API key.
- Send it on every request as a header
Authorization: <key> - The exact header isn't documented — Authorization is a common default; confirm in the provider's docs.
Your key is stored only in this browser (localStorage) and sent directly to the API — never to greatapis.
